Pierrick Bouvier 0340d819d0 target-info: introduce TargetInfo in QOM ...

For the single-binary, we want to be able to retrieve at runtime the
current target among the different ones available.
A consequence is that we can't rely on existing target_info() definition
since it will create a conflict once more than one target is available.

To solve this, we add TargetInfo in QOM, with this hierarchy.
We define one class "target-info-X" per target, that inherits from
abstract class "target-info". Using concrete vs abstract class ensure we
can easily filter "target-info-X" from all QOM types.
Associated TargetInfo is directly set through class initialization,
without relying on any instance.

For user mode, we simply define target_info() like it was done
previously. In this patch, we keep the same definition for system-mode
also, and it will be replaced in next commits.

We will introduce detection of target from QOM, so we need to make sure
those types are registered early.
